Abstract:
A land-cover classification is needed to deduce surface boundary conditions for a<br/> soil?vegetation?atmosphere transfer (SVAT) scheme that is operated by a<br/> geoecological research unit working in the Andes of southern Ecuador. Landsat<br/> Enhanced Thematic Mapper Plus (ETM + ) data are used to classify distinct<br/> vegetation types in the tropical mountain forest. Besides a hard classification, a<br/> soft classification technique is applied. Dempster?Shafer evidence theory is used<br/> to analyse the quality of the spectral training sites and a modified linear spectral<br/> unmixing technique is selected to produce abundancies of the spectral<br/> endmembers. The hard classification provides very good results, with a Kappa<br/> value of 0.86. The Dempster?Shafer ambiguity underlines the good quality of the<br/> training sites and the probability guided spectral unmixing is chosen for the<br/> determination of plant functional types for the land model. A similar model run<br/> with a spatial distribution of land cover from both the hard and the soft<br/> classification processes clearly points to more realistic model results by using the<br/> land surface based on the probability guided spectral unmixing technique.
